175 m³/min Energy-saving Turbo Vacuum Pump System for Wastewater
Treatment
Product Introduction
GoodSeaA centrifugal vacuum pump adopts variable frequency
technology, which can adjust the speed of vacuum pump, adjust the
power with the change of parameters of paper production line, and
keep vacuum pump always working in the best operating condition.
GoodSeaA vacuum system is a completely customized design. The most
reasonable vacuum point design is selected according to the user's
paper machine operation. The vacuum degree proximity point, suction
point is combined to make the high-speed centrifugal vacuum pump
efficient and always run at high-efficiency zone of the pump’s and
the motor’s characteristic line, it is equivalent to the aircraft
flying at the most fuel-efficient cruising speed.
GoodSeaA centrifugal vacuum pump has three centrifugal pumps:
single-stage, two-stage and three-stage. One equipment has multiple
suction ports and can pump two different vacuum degrees. Therefore,
a high-speed centrifugal vacuum pump can replace multiple water
ring vacuum pumps, it has compact structure and many adjustable
output parameters.
GoodSeaA vacuum system provides complete equipment and system
solutions: including water-air separator, cooler, filtrate pump,
silencer, valves, meters, fittings and fully automated control
systems for online monitoring of vacuum degree and pumping flow.

Commissioning & Testing
High Speed Dynamic Balance Test
Gradually balancing from low speed to high speed.
The equilibrium speed is as close as possible to the critical
speed.
Balance at rated working speed to ensure balance accuracy.
Rotor Test
The wheel rotation fracture test is carried out without damage in
the ground with 122% maximum rotational speed.
Working on the engine at 115% maximum allowable steady-state
operating speed for 5 minutes without cracking and the size is
within the allowable range.
On the engine, exceed the maximum allowable average steady-state
temperature of 42℃, work for 5 minutes without cracking, and the
size is within the allowable range.
Vibration Test
20% margin between critical speed and maximum working speed.
During the test of the components and the whole machine, there is
no adverse reaction to the vibration in the working speed range.
Performance, Characteristic Test
Performance tests under design conditions.
Characteristic tests under non-design conditions.
Process the test data to determine whether the performance of the
component is up to standard and draw a characteristic curve.
